"This talk was "fantastic."
"I enjoyed seeing the historic photos compared to what is there today and hearing stories from one whose relatives lived and ranched here."
"On a scale of 0 to 10, this program was a 12! I would tell a friend about this event because I learned things tonight that I could not have learned anywhere else."
"I enjoyed learning about how the dam was built and how they had to move old Dillon. Our guide was amazing! She presented so much information in an hour and half. What I liked best was seeing the eagles and deer along the shore. Unfortunately, I forgot my camera!"
